| Description |
Fosinopril (SQ28555) is the ester prodrug of an angiotensin-converting enzyme (ACE) inhibitor with the IC50 value of 0.18 μM[1]. Fosinopril demonstrates a non-competitive inhibition effect on ACE activity with a Ki value of 1.675 μM[2].

| In Vitro |
Fosinopril (0, 1, 10, 33, 100μM; 30 min) partially inhibits the cosedimentation of liposomes and recombinant LPLA2[1]. Fosinopril (250 nM) shows no inhibition of the soluble esterase activity of LPLA2[1]. Fosinopril (0.372, 0.744, 1.116 μM) displays a non-competitive inhibition effect on ACE activity with a Ki value of 1.675 μM[2].

| In Vivo |
Fosinopril (orally; 4.67 mg/kg; 4 weeks) downregulates the creatine kinase (CK) and lactate dehydrogenase (LDH) levels and against cardiac dysfunction and structural alteration[3]. Fosinopril (orally; 4.67 mg/kg; 4 weeks) suppresses cleaved-caspase 3 expression and myocardial apoptosis in AMI rat model[3]. Animal Model: HF post-acute myocardial infarction (AMI) rat model (SPF-grade Sprague-Dawley (SD) rats, 265 ± 15 g) [3] Dosage: 4.67 mg/kg Administration: p.o.; 4 weeks Result: Against cardiac dysfunction and structural alteration and suppressed apoptosis.
